Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Description fails to disclose any behavioral traits beyond the name. No annotations exist, so the burden is entirely on the description, which offers no information about side effects, permissions, or irreversibility.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Extremely concise at 4 words, but this is under-specification rather than effective conciseness. The description lacks structured details that would aid an agent.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 8 parameters, 4 required, and no output schema, the description is woefully incomplete. It omits response format, error conditions, and parameter formatting guidance.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With schema description coverage at 13%, the description adds no meaning to parameters. It does not explain access_token, the difference between self and link, or the purpose of optional fields like text, url, nsfw, etc.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Create a Reddit post' clearly states the verb and resource, distinguishing it from siblings like reddit_comment or reddit_search. However, it lacks details about what kind of post or the process.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. No prerequisites, use cases, or when-not-to-use advice provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
